Sound insulation Alternative

[BDiefAZ]

I used the following product to insulate the cab of my truck over the last 2 weeks following the install of a new driver's side window motor:

http://www.lowes.com/lowes/lkn?action=p ... 1410-FV516

It is available at either Lowe's or Home Depot. The material comes in a roll, 1/8 inch thick self adhering foam, with a foil front on a 15 foot roll. Basically cut, peel, and stick like the other materials but at a fraction of the cost.

I am not claiming it to be like dynamat in its performance, but it does a great job for what it costs. I spent just under $30 for the whole area for 2 - 15 foot rolls.

The whole project used 2 rolls of the product on the doors and rear panel of the cab following tire jack bracket removal. The end result is that it is easy to use, relatively inexpensive, and reduces alot of road and outside noise in the truck. I only applied one layer of the material, and only placed it on the lower level of the inside of the door to avoid contact with the window mechanism. Some material was also placed on the back side of the door panels. The doors sound much more solid when they close.

I would like to remove the extended cab interior panels and cover those surfaces as well, especially since the front speakers now sound better and stronger than the rear speakers.

Hope this helps.

That link didn't take me to the product. How about a good link and description of the product. Pricing would be good as well as a part number.

I fixed the link, but in short, it is just under $15 per roll

So it has a self adhesive on the foam side correct?
Looks like pretty good stuff. Thanks for the tip.

Keep in mind that foam can absorb water and create a real problem in areas where moisture is prevalent.
I know of a couple rigs where they rusted out the doors using foam rubber as a sound deadener.

[BDiefAZ]

It is self adhesive.

Good point, seems to be pretty "closed cell", but caution should used in potentially wet areas.

Isn't there some sort of commercial spray in sealant stuff that would do the same thing, but also permanently cure and bond to the surface it's sprayed on to prevent any rusting?

Seems like they'd have that somewhere...

I would guess spray under coating. If I remember correctly Jim did the inside of his doors. Jim?

I know they have the spray you're talking about for home insulation use. It expands after you spray it but I've never heard of its use for automotive and I don't know if it would prevent rust but assuming it keeps air out than it should. The spray undercoating wouldn't really help with insulation so much but rust prevention definitely.

[Rockrz]

Yeah, if you used the undercoating spray on the inside...it'd probably make your truck stinketh

I bought a "starter kit" from R-Blox off of eBay for 'bout $30 + shippin and got 25 square feet of material.

I'll bet this stuff is the same stuff...only, much less expensive.

Heck, I'm thinkin 'bout buying this stuff from Lowes and marking it up to make a few bucks!
All you have to do is come up with a marketing plan, and rebox the stuff and you've got a great automotive product!

I'm going to get a roll of this and put it inside the doors of my wife's Cavalier and see how it does.
I may even go plum overboard and remove the seats and carpet and door the floors!

This Reflectix from Lowes has got 2 -3 years on it under my hood. Used stock fasteners and 3m double sided take and it has held up well. Brule saw it in October and it was in good shape but, he'll probably claim that I just reapplied it! It is cheap bubble wrap covered with foil. If, you get bored, just start mashing the bubbles to irritate people.
